9 Claims.

This invention relates to a flanged wall coping.

' The invention aims to provide, in a manner as hereinafter set forth, a coping designed primarily as a protecting means for the top of a parapet wall, but it is to be understood that a coping, in

accordance with this invention is for employment in any connection for which it may be found applicable.

The invention further aims to provide, in a manner as hereinafter set forth, a coping for the purpose referred to including a pair of internal pads for seating On and so formed for the reception of cementitious material for looking or securing them to the top of the wall.

The invention further aims to provide, in a manner as hereinafter set forth, a coping for the purpose referred to including a plurality of com plemental units disposed in endwise aligned arrangement, and with the units having means for overlapping and interlocking to coupling them together in the manner aforesaid.

The invention further. aims to provide, in a manner as hereinafter set forth, a coping unit including a high end portion having its inner face formed throughout with a key, and a low end portion having its outer face formed throughout with a key receiving channel.

The invention further aims to provide, in a manner as hereinafter set forth, a coping unit in- 30 cluding a body part of arcuate cross section, side flanges depending from said body part and spaced parallel depending lengthwise grooved seating pads on the inner face of said body having their seating faces aligned with the upper end of the inner facesvof the flanges.

The invention further aims to provide, in a manner as hereinafter set forth, a flanged coping uni-t having spaced parallel depending portions on its inner face each formed lengthwise thereof 0 with a substantially dovetailed groove in proximity to a side of the unit for'the reception of cementitio'us material for securing the unit in overlapping relation with respect to the top of a parapet wall.

The invention further aims to provide, in a manner as hereinafter set forth, a double flanged coping formed of a plurality of complemental overlapping interengaging units forming a smooth surface on the outside of the wall with which the coping is correlated; each unit including spaced internal pads for seating it on the wall and an internal key inwardly of one end and spaced from one end of the pads, each unit having its pads formed with grooves for the reception of cement to secure the pads on the wall, and

each unit being provided with a peripheral groove at its other end running the full length'of the lap as well as down a flange for coaction with a leakable, and comparatively inexpensive to manufacture.

Embodying the aims aforesaid and others which may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts as will be more specifically described and illustrated in the accompanying drawings, wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawings:

Figure .1 is a fragmentary view in side elevation of a coping in accordance with this invention, installed with respect to a parapet wall,

Figure 2 is a section on line 22 Figure 1,

Figure 3 is a view looking towards one end of a coping unit,

Figure 4 is a view similar to Figure 3 looking towards the other end of the unit,

Figure 5 is a fragmentary view in longitudinal section of the coping, and

Figure 6 is a fragmentary bottom plan of a unit.

The flanged wall coping will consist of a plurality of overlapping interengaging complemental units preferably constructed from clay, but it is to be understood that the units may be formed from any suitable material.

With reference to the drawings, l indicates a parapet wall and 2 the top of the latter. 3 indicates generally the flanged coping arranged relatively to the top and sides of wall I. The units of the coping 3 are of like form and designated 4. Each unit 4 consists of a body part 5 of arcuate contour in transverse cross section formed of a high portion 6 and a low portion 1 of materially less height, length and width than the portion 6 (Figure 5). The top of portion 1 is arranged below the top of portion 6 to thereby provide a shoulder 8 and a seat 9. The shoulder 8 is positioned' inwardly of an end of body part 5' and is into the portion I whereby the said portions are connected together. Depending from the sides of the portion 6 is a pair of flanges I I. Depending from the sides of the portion I is a pair of flanges I2 of less width than and which merge into the flanges II at the point of joinder of the part II) with portion 1. The bottom of the flanges II, I2 are flush with each other. As the flanges I2 are inset with respect to the flanges II, the outer sides of flanges I2 form downward continuations of the shoulder 8.

The seat 9 from end to end thereof is formed with a transverse semi-circular groove I3 and the outer side faces of the flanges I2 are provided with downward continuations I4 of the groove I3. The inner face of the portion 6 in proximity to its end I5 is formed transversely with a depending continuous semi-circular key I6, and the inner faces of the flanges I I are formed with depending continuations I1 of the key I6.

Each unit includes a pair of spaced parallel depending pads I8, which are formed integral with the inner faces of the said portions 6, I. The pads I8 extend from a point inwardly of the end I5 and key I6 of portion 6 to the free end of the portion 1. The pads I8 throughout are formed with dovetail grooves I9 opening centrally of the bottoms thereof. The pads are for seating on the 4 top of wall I, and the flanges are for disposing at opposite sides of the wall.

When the coping is arranged relative to the wall I, the pads I8 are secured to the latter by a body of cement 20 deposited on the top 2 of the wall I at each side of said top. The cement 20 extends into the grooves I9 of the pads I8, engages the lower face of the pads, is forced by compression against the upper portion of the sides of the wall I (Figure 2) and extends intocontinuations I4 of the groove I3. When a unit of the coping is arranged relative to an adjacent unit the end I5 of a portion 6 of one unit overlaps the portion 1 of an adjacent unit, and the key and its continuations seat on the groove I3 of an adjacent unit, as well as the continuations I4 of such groove, whereby the units are not only overlapped, but are interengaged and locked together, the cement assisting for such purpose. When the units are disposed in overlapping relation the end I5- of the portion 6 of one unit abuts the shoulder 8 formed by an end of the portion 6 of an adjacent unit.

Each unit includes what may be termed a onepiece body formed of a pair of inverted U-shaped parts; one of greater length, width and height than the other. Each of said parts includes what may be termed a bight and a pair of arms. The part of smallest length having its outer face inset throughout with respect to the outer face of the other of said parts, thereby forming said body with a peripheral shoulder between its transverse median and one end. The part of greatest height being formed on its inner face in proximity to from a point removed from one end of said body to the other end thereof.
